I disconnect DSR 11 and replace by the camera HVX 200, with MiniDV play back.
NO EFFECT, the same as previousy.

FCP grabs the firewire ports when it launches, it doesn't like it if you connect a firewire device whilst FCP is running. Try connecting the DSR 11, switch it on and then launch FCP. It should then see the deck or camera when you go to log and capture.

From the Apple menu go to "about this Mac" >More info
Go to Firewire.
Any connected firewire devices should be listed, if not then you have a faulty cable or Firewire port.
